CLAIR DENNISON LAKE, or BINGHAMTON, new YoRK, ASSIGNOR TO THE TABU- LATING MACHINE COMPANY, A. CORPORATION or- NEW JERSEY- PRINTING-TABULATOR.

Specification of Letters Patent. I Patented lylay 24, 1921.

Application filed December 29, 1919. Serial 170,348,069.

To allwhomz'tmay concern: v I Be it known that I, CLAIR D. LAKE,'a citizen of the United States, residing at Binghamton, inthe county of Broome and State of New York have invented certainnew and useful Improvements in Printing-Tabulators, of which the following is a full clear, and exact description.

The invention which forms the subject of this application for Letters Patent-is an improvement in attachments for, tabulating' machines, more particularly thewell'known V d1cat1ng wheels which are set to'indicate the onding to the perforations; 1

and widely-used Hollerith tabulato'r, which is typicaljfbf the general class of machines designed solelygfor tabulating.

This machine. is set forth in numerous...

patents-but is', perhaps, more fully shown and described inPatent No. 685,608,, dated Oct. 29, 1901.

In' such machines provision is made for passing singly and in rapid succession a stack of perforated cards under a. series of brushes or contacts which, encountering perforations, make contact with a conductor over which the cards pass, and thereby energize electromagnets to operate suitably designed and constructed means for indicating the data which the perforations by their number or location represent. vGenerally. speaking, the miain function of such machines is to totalize items and when a de- '"termined number of 'cardshas been run through, theindicated totals may be read off and taken down. No provision. as a rule, is made for printing or permanently recording the individual items, as this requires more time, and a slower operation of the machine than its normal use will permit.

Hence, to list the items indicated by a stack v of cards, would involve the reading. and

recording of each figure displayed by the record Wheels.

My purpose has been to extend the field of usefulness of such machines, and to provide means whereby they may be called upon, when occasion requires, toli'st or print the items and toprint'or record Subtotals and totals, and ingeneral to make-a permanent record of whatever operation they may be called upon to perform. With this object in mind I have devised an attachment to a tabulator which will operate in synchronism or exact accord therewith to record each item, subtotal or grand total as the case may be, and to adapt the tabulator' to numbers corres in the cards.

individual cal devices, and combinations, and in these the. inventlon resides. The general nature.

of the improdement may thereforebe gathered from 'fthe consideration that in the tabulator proper there area numben'of iny new attachmentj is-capablei of printing each numberso indicated, the totals of a group of suchnumbers r the grand totals of several-groups; vided with means for resetting,-

ing wheels to zero after any 'for'jany number}.

of'opera'tions, so that after" resetting /I 1o} totals'may be preserved, or on thebotherl hand, if not reset, a subtotal maybe printed;

printedtotal As above stated,'there is used-a coiltroL' and preserved,.-so that the next will be a grand'total and so on.

ling device by whichthe speed'of thetabulator is'reduced when the attachment is used .,ior listing, but if only totals are to be print -.;'ed, then.

the machine-[may be set ;.fe1- the higher or normal tabulator speed, and; the

tals beingre'corded by pressing, a. button, which causesthe proper mechanis 7 fd-lthe purpose to operate.- The .,-in1pro-vement is illustrated in detail in the accompanying drawings:
